Super Bowl Sunday is a long-awaited moment for sports fans across the US — but it’s also an indicator of how the year’s housing market will perform.

That’s according to Glenn Kelman, CEO of the online real-estate brokerage Redfin, based in Seattle.

NPR’s Stacey Vanek Smith spoke to Kelman last month on a segment of the podcast “The Indicator From Planet Money.” When Smith asked him if he expected 2018 to end with a whimper or a bang, Kelman gave an answer that was simple but definite: a whimper.

While the downward trend could smooth out in 2019, “a deeper drought in housing is dark news for just about everybody, not just the banks,” Business Insider’s Alex Morell reported. “Significant housing declines have foreshadowed nine of the 11 post-World War II recessions in the US, according to another note by UBS from December examining the housing slowdown.”

And there’s one weekend that Kelman says will indicate the direction of the market: the weekend of the Super Bowl, which is this Sunday.
